Identify the chemical formula given: CoCO3.
Recognize that Co represents cobalt and CO3 represents the carbonate ion.
Determine the charge of the carbonate ion, which is -2.
Since the compound is neutral, the charge of cobalt must balance the -2 charge of the carbonate ion. Therefore, cobalt must have a +2 charge.
Name the compound by stating the metal first with its oxidation state in Roman numerals, followed by the name of the polyatomic ion: cobalt (II) carbonate.
